CORN-SEPARATING DEVICE FOR CORN-HUSKERS.

SPECIFICATION forming part of Letters Patent No. 738,321, dated September 8, 1903.

Application filed January 23, 1902. Serial No. 90,873. (No model.)

To all whom it may concern:

Be itknown that I, WILLIAM GUrnNKUNsr, a citizen of the United States, residing at Milwaukee, county of Milwaukee, and State of Wisconsin, have invented new and useful Improvements in Corn-Separating Devices for Corn-Huskers, of which the following is a specification.

My invention pertains more especially t the combination and arrangement, with the discharge duct which communicates from the corn husker and shredder to the fan-inclosing case, of a so-ealled vacuum-chamber, through which air is drawn from the exterior by the action of the stalk-elevating fan, whereby the dust is separated from the shelled corn as it falls from the screen in said duct in its passage through said vacuumchamber; second, to the device for elevating the shelled corn and discharging it into a receptacle therefor after the dust has been separated therefrom.

The construction of my invention is explained by reference to the accompanying drawings, in which" 7 Figure 1 represents a side view partly in section, and Fig. 2 is a front view thereof.

A represents the dischargeend of an ordinary corn husker and shredder.

B is a fan, and O the fan-inclosing case, by which the shredded stalks passing through the machine are elevated.

D is the discharge-duct of the fan-inclosing case.

Interposed between the rear end of the machine proper and the fan-case O is a screeninclosing case E, through which the shredded stalks are drawn from the machine by socalled vacuum-pressure produced by the fan B, whereby the shredded stalks are drawn into the case 0 and discharged therefrom, as stated.

For the purposesof my present invention the screen employed for separating the shelled corn from the shredded stalks may be either reciprocating, revolnble, or of any other desiredconstruction which may best subserve the purpose intended. The lower side of the inclosing case E is provided with a partial 5o vacuum-chamber F, through which the corn thence is discharged into the transverse duct I.

It will of course be understood that as the fan B is operated a partial vacuum is formed within the screen-inclosing case E and chamber F, whereby a strong current of air is led from the exterior into said case and chamber through the passage J beneath the screen, whereby the dust and other refuse matter escaping from the screens above are drawn by said current of air up into the fan-case O and discharged therefrom with the shredded stalks. Thus it is obvious by this construction that I am enabled to utilize the same fan for separating the dust from the shelled corn that is used for elevating the stalks, whereby a separate fan heretofore employed for such purpose is avoided.

K is an elevator into the lower end of which the shelled corn is led through said duct I,

when it is elevated by the series of buckets L L to the top of the elevator and discharged therefrom through the spout M into a sack or other receptacle provided therefor. The se ries of buckets L L are supported in the or dinary manner from an endless belt N, which belt is in turn supported at its respective ends by ordinary pulleys O, one-of which is shown at the lower end of said elevator. Motion is communicated to said elevator from a moving part of the husker and shredder through the belt P, pulley Q, and shaft R, whereby as said machine is operated the shelled corn, which has been incidentally loosened from the ears during the process of husking, is not only screened out and separated from the stalks, but the dust and other foreign matter that escape through the screen are entirely removed therefrom by the current of air which is drawn into the screencase, while the corn which has been thus separated and cleaned is simultaneously elevated and discharged into sacks or other receptacles therefor.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is r The combination with the fan and the dis- In testimony whereof I affix my signature charge-duct through which the stalks are led in the presence of two witnesses. to the fan of a vacuum-chamber located beneath and connected with the lower side of WILLIAM GUTENKUNST' 5 said duct', and a screen located within said Witnesses:
